IN January 2019, Chinese spaceship Chang’e 4 The lunar-visiting mission, figuratively, opened up a new horizon by landing on the other side of the orb, which is permanently invisible to Earth and therefore invisible to direct radio communications. This means that communications had to be relayed by satellites cleverly placed for the purpose where the interaction of the Earth’s and Moon’s gravitational fields could orbit points in empty space. did.
In contrast, China’s next lunar mission will literally land. Chang’e 5Is scheduled to be launched around November 24, with the aim of digging 2 meters into the surface of the moon, collecting about 2 kg of rock, and returning it to Earth.If successful, it is the first month sample return mission since 1976, and the Soviet spacecraft Luna 24 I sent back only 170g. And that would be another step forward in China’s space program.
The· Change The mission, named after the Chinese moon goddess, had ups and downs. Chang’e 5 Initially scheduled to explode in 2017, in July of that year a otherwise unrelated project failed. Chang’e 5, Long March 5 was used as a rocket, causing a delay. (((Chang’e 4 I used another kind of launcher, the Long March 3B.. However, “go” seems to have been given now.State media rocket on November 17th Chang’e 5 The cabin was moved to the launch pad of the Wenchang Space Center on Hainan Island.
Assuming the launch went according to plan, success depends on a complex ballet that includes the four components of crafting. These are service modules, return to Earth modules, lunar modules, and ascenders. These are the configurations originally used in the Apollo program in the United States. When the mission enters the lunar orbit, the lander and ascender separate from the orbiting mothership, return the module as a unit, and land on the surface. The landing site is located in the northern part of the vast basalt called Oceanus Procellarum, an area that has never been visited before. Researchers confirm that the rocks collected here continued to be volcanic on the Moon until much more recently than 3.5 billion years ago, an estimate derived from studies of currently available samples. I hope that.
When new material is collected (which can take several days), the ascender takes off, docks with the mothership and transfers its transport to the return module. The service module will then take the return module back to Earth, release it shortly before arrival, and land in December at the Inner Mongolia recovery site, which is also used for Chinese crew missions.
However, digging into the lunar surface can cause problems. InSightThe American rover, now on the surface of Mars, is struggling to operate a drill called a “mole” designed to reach 3 meters underground.by NASA, American Space Agency, because the mole encountered a more massive regolith than the designer expected and bounced off instead of digging a hole.
If Chang’e 5 So far, China has succeeded in overcoming such dangers and returning samples to Earth, but has made little to say which foreign countries are allowed access to them. But America can be the last in the queue. For the past few decades, the US government of all stripes has been reluctant to work with China on space-related issues, primarily because of fear of giving secrets to help design ballistic missiles. In space, as in many other cases, the two forces are less friendly rivals. China’s stated goal is to establish a crew base near the Moon’s South Pole. There, water is available in the form of ice, which is permanently shielded from sunlight by the walls of the craters. There are similar plans in the United States. Look at this space, so to speak.■■
